Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
Hello,
is it possible to use a external clock e.g. a digital output of a TXCO. As source for the LF clock. So the same clock source as used for the host uC can be used...
Hi!,
I'm newbie with nRF52. I have a nRF51 Development Kit and a nRF52 Development Kit.
I have installed nRFconnect (for Ubuntu 64 bits) in Fedora 24 Workstation (64...
Hi! I have tried to use USB CDC ACM in my project but after running the USB CDC ACM example in the SDK, I found out that the example have the issue of not sending the data...
Hello,
So I'm constantly reading data using i2c into a variable. How do I transfer the data in this variable to the pc? It's just an array.
I understand that I have...
I am looking for a smallest size transceiver with an antenna done as part of the PCB layout (no external antenna needed). The simplest RF PCB layout is preferred, single frequency...
Hi, I purchased a Sparkfun Breakout board for the NRF52832, but the bootloader on it seems to be extremely unstable. Hence, I've decided to flash the NRF52832 directly from...
Hello,
I already checked below link, but want to clarify the limitations of how many concurrent sessions are allowed in Soft Device initialize.

Hello,
i add a new custom service with one characteristic that allows me to send values over BLE with nRF connect, but i must send some acceptable values (-2, -4, 0, 4, 10...
Using SDK14.0.0, nRF52832, GCC, GDB/Ozone, secure DFU
This question seems to get close to asking about my problem.
I am trying to debug my application with a loaded...
Hi,
We made a custom PCB using the NRF52832 and followed the reference design. While everything else is working in our system, the BLE part is not working. We are using...
Hello,
I try to develop an application on a nRF51802 device. But this device is not managed in nRF_Drivers.4.0.0-2.alpha.pack from Keil software.
Is there an update...
Hey guys! Like the title says, I'm looking for the best way to send values like humidity and VOC from the Nordic Thingy to the cloud. I have already set up the thingy to send...
Does anyone know of an off-the-shelf hardware and software that will let me read and write nRF52832 devices that are using the NFC Type 4 Library? We've tried the ACS ACR1252...
Materials publicly available say the chip works from 3.1 volts.
But is this the absolute minimum voltage or will it be possible to use also LiFePO4 battery cells with the...
